Specification of Letters Patent.

Patented July 8, 1913.

Application filed April 1, 1912. Serial No. 687,687.

To all whom, it may concern Be it known that I, GEORGE A. Tnnxnn, acitizen of the United States, residing at Kane, in the county of McKeanand State of Pennsylvania, have invented certain new and usefulImprovements in \Voodworking- Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates ,to improvements in wood-working machines-theobject of the invention being to provide a machine which will operateaccurately to bevel and round the ends of the head of a brush handle.

WVith this object in view, the invention consists in certain novelfeatures of construction and combinations of parts as hereinafter setforth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of a machineembodying my improvements; Fig. 1 is a view of a handle blank; Fig. 1 isa view of the handle after the ends of the head have been beveled; Fig.2 is an end view; Fig. 3 is a side elevation; Fig. 1 is a longitudinalsectional View; Fig. 5 is a side elevation of the carriage; Fig. 6 is aplan view of the carriage; Figs. 7 to 13 inclusive are viewsillustrating various details; Fig. 14 is a view in section on line (r nof Fig. 1; Fig. 15 is a section on line 6-4) of Fig. 1.; Fig. 16 is aview on the line cZ-cl of Fig. 1; Fig. 17 is a view on the line f-;' ofFig. 1; Fig. 18 is a view on the line e--@ of Fig. 1, and Fig. 19 is anend view of the carriage and some of the cooperating parts.

1 represents a frame provided with a table 2 having an opening 3, and onsaid table. alining guideways 15 are located, each of said guidewayscommunicating at its inner end with the opening 3. The walls of theguideways 4 5 are undercut to accommodate the dove-tail base portions6-7 of a carriage 8, which latter also includes in its structure, anarrow and deeper portion 9 depending through the opening 3 in thetable. One side portion of each guideway, 1-5 is made adjustablelaterally and held in position by means of set screws 11-12.

Located upon the portion 6 of the carriage 8, is a plate 13 havingtherein, an elongated slot l l for the accommmlation of a bolt or screwsecured to the carriage for the purpose of securing said plate at anydesired adjustment. Near its forward end the plate 13 is provided with aplurality of perforated bosses or sockets 16, in one of which, the shankof a bifurcated support 17 is supported as shown in Fig. land secured inposition by a set screw 18 as shown in Fig. 15. The bifurcated support17 receives the shank portion of a brush handle 19, the head portion 20of said handle resting upon a. block 21 adjustably secured to theintermediate part 9 of the carriage and provided with a shoulder 22against which the forward end of said head 20 abuts as clearly shown inFig. 4. The handle 19 is held in position on the supports 17 and 21; andbefore said handle is firmly clamped; by means of spring jaws 232-l.These jaws are mounted on the plain portions of screws 25 secured inbosses 26 located at the side edges of the plate 13 intermediate theends of the latter as shown in Fig. 7. The forward ends of the jaws23-2-1 are curved and engage the sides of the handle 19 at the junctureof the shank and head thereof as shown in Fig. 1-thus serving to holdthe handle against lateral displacement and to insure the properpositioning of the handle before it shall be clamped as presentlyexplained. The jaws 23-2-it a re moved toward the brush handle b the oeration of iinions 27 to which said jaws are adjustahly secured by meansof set screws 28. The jaw 24: is made with an integral arm 29 which hasa general U-shape and its free curved end 30 bears against a rail 31. Aloop 32 embraces the curved portion 30 of the arm. 29 and the rail 31and this loop is connected, by an arm 33 with which it is integral, withthe intermediate portion of said arm 29. The rail 31 comprises twoportions disposed in paral lel planes, and a diagonal intermediateconnecting portion 34: which constitutes. in effect, a cam for operatingthe spring jaws 23-2 1, through the medium of the U-shaped arm 29 andthe pinions 27, when the carriage 8 is reciprocated.

A bifurcated standard 35 rises from the carriage 8 at or near the innerend of the portion 7 of the latter, and in this standard, a lever 36 ispivotally supported between its ends. The lever 36 is provided at oneend with a head or enlargement 37 and the latter is made with aguide-way 38 for a vertically movable clamp-block 39 carrying a pivotedjaw 40 to engage the head 20 of the brush handle 19 and hold the samefirmly on the block 21 during the cutting operation hereinafter to bedescribed. The clamp-block 39 is connected with the lever head 37 bymeans of a headed screw 41 secured to said clamp-block and movablethrough a vertical slot 42 in said lever head 37. The clamp block 39 isprovided with a lug 43 having a threaded hole for the passage of ahandoperated screw 44. The plain upper portion of this screw 44 passesfreely through ahole in a lug or projection 45 on the lever 39 and isprovided with a hand wheel 46. The screw 44 is also provided, at theintersection of its threaded and plain portions, with a fixed collar47,between which and the lug 45, a spring 48 is located and serves toforce the aw 40 against the head 20' of the brush handle with a yieldingpressure, when the parts are in the positions shown in Fig. 4.

The rear end of the short arm of the lever 36, is connected with a link49 and the latter is connected by a rule-joint With one arm of a lever50. This lever. is pivotally. mounted on a suitable support 51 risingfrom the carriage 8 near the rear end of the latter, and the shorter armof said lever 50 is provided with two lugs 5253 to be engaged by atrippin 54 carried by a block 55 adjustably secured in a guide-way 56 on thetable 2.

In the drawings, the carriage is shownin a position intermediate theends of its travel. As the carriage 8 moves backwardly from the positionshown in Fig. 4, the lug 52 of lever 50 will engage the trip pin 54 andsaid lever will be turned on its fulcrum, causing the upper end of saidlever and the lower end of the link 49 to move back and the lever 36 tobe'turned on its fulcrum to raise the clamping jaw 40 and release thehead of the brush handle.

For reciprocating the carriage 8, a cam 57 is employed, said cam beingconnected through the medium of a bell-crank lever 58 and alink 59, withthe carriage as clearly shown in Fig. 1. The cam 57 is secured to ashaft 60 carrying a worm wheel 61 and the latter receives motion from aworm 62 on a shaft 63. A pulley 64 is secured to the shaft 63 andreceives motion from any suit able source of power.

The intermediate portion of the carriage 8 is provided on its lower edgewith a dove-tail rib or flange 65 to enter a simi larly-shaped groove 66in a guide orcam plate 67 and support the latter'at the bottom of thecarriage. The rib or flange 65 is notched for the accommodation of thedovetail head 67 of a bolt 68,Which'latter passes upwardly through thecarriage and is provided at its upper end with nuts 69. This bolt servestosecure the guide or cam plate to the carriage at any desired positionof longitudinal adjustment. As shown in Fig. 10, the guide plate 67 isconstructed at each side with edge portions 7 O-7 l in parallel planesand a diagonal edge portion 72 connecting the edge portions 7 O and 71.The guide or crank plate 67 serves, by reason of its form as abovedescribed, to control the feeding of the cutters toward the Work, aswill be hereinafter explained.

Two arms 7 37 3 are pivotally connected with the frame-work near theforward end thereof and extend under the table2 toward the centralportion of the frame-work, said arms terminating at their inner ends inheads 74 having dove-tail grooves, in which vertically movable bars 75are disposed. Each bar 75 is provided with bearings for a vertical shaft76, which isprovided at its upper end with a cutter head 77 and betweenits ends with a pulley 78. The cutter heads are located over the opening3 in the table 2 and at respective sides of and laterally beyond thecarriage 8 as clearly shown in Fig. 1. The head 74 of each arm 73 ismade with an opening 79 (Fig. 3) through which a lug 80 on the bar 75,passes. A lug 81 is also made at the lower end of each head and in saidlug 81 a vertical screw'82 is swiveled the threaded'portion of saidscrew passing through a threaded hole in the lug 80 of bar 75. Eachscrew 82 is provided at its lower end with a hand wheel 83 for operatingthe same to effect vertical adjustment of the cutter heads. A bar 84 isadjustably attached to the head 74 of eaClfarm 73 by means of a screwbolt 85, the bar being provided with an elongated slot through whichscrew bolt passes. At the inner ends of the bars 84, rollers 86 aremounted to run against the side edges of the guide or cam plate 67, andat their outer ends, said bars are provided with lugs 87 having threadedholes for the aassage of screws 88 for adjusting the bars 84 and therollers 86, said screws passing through lugs 89 on the heads 74 andprovided hand Wheels 90 for turning them. Belts 91 (from any suitablesource of power) pass about the pulleys 78 for driving the shafts 76 onwhich the cutter heads 77 are secured and these belts are so disposedthat they will. tend to cause the rollers 86 to bear against the sideedges of the cam plate 67 and to cause the cutter heads to move towardeach other when permitted to do so by the cam plate.

As previously stated, the purpose of the machine, is to bevel and roundthe ends of the heads of brush handles, and in accomplishing this, themachine will be operated as follows :The work to be operated upon is ahandle having the configuration shown in Fig. 1 the ends of the headportion 20 being approximately square and at right angles to the freeforward edge of said head. The supports 17 and 21; the cam rail 31; andthe cam plate, will be first adjusted in accordance with the length ofthe handle to be operated upon, and the rollers 86 will be adjusted toinsure the proper extent of cut to be made at the ends of the handlehead. The work, consisting of a handle such as shown in Fig. 1, willthen be placed in position with the shank portion resting upon thebifurcated support 17 and thehead portion resting upon the block orsupport 21 and abutting against the shoulder 22. The application ofpower to the shaft ()0 will cause rotation of the cam 57 and the latterwill (during a portion of its rotation) impart motion, through thebell-crank lever 58 and link 59, to the carriage 8 to move the latterforwardly and said cam will also ope ate (during another portion of itsrotation) to move the carriage backwardly so that during the operationof the machine and during another portion of the rotation of the cam thecarriage will remain idle to permit removal of finished handle and in--sertion of a blank. The work having been placed in the position abovementioned when the carriage approximates the back end of its travel, theU-shaped arm will move on the cam or diagonal portion 34: of the rail 31and cause the spring jaws or fingers 232-.L to move from their openpositions to the positions shown in Fig. 1,the said spring jaws 0rfingers being thus caused to engage the work and properly position thesame on its supports 17 and 21 and said jaws or fingers will remain incontact with the work during the remainder of the forward travel of thecarriage and until the end of the U-shaped arm 28 reaches the portion 34of the cam rail 31 during the forward movement of the carriage. Afterthe work has been positioned by the spring jaws or fingers 2. 2t andduring the forward movement of the carriage, the trip pin 54 will beengaged by the lug or toe 53 of lever 50 and move said lever to theposition shown in Fig. 4, thus operating the lever 36 and causing theclamping jaw 40 to engage the head 20 of the work and hold it firmly toits seat on the block 21. The work having been properly positioned andclamped, the carriage is caused, by the operation of the cam 57, tocontinue to move forwardly, and carry the work between the cutter heads77--77. During such forward movement, the cam plate (37, moving incontact with the rollers 86, will permit the arms 73 to turn on theirpivotal supports and the cutter heads to move away from each other andthe line of travel of the ends of the head 20 of the work, while camedges 72 are passing said rollers. The outward movement of the cutterheads is limited by the width of the wider portion of the cam plate 67..It will be observed that the work will travel in a straight line andthat at the same time (and while the work is being subjected to theaction of the cutters) the cutter heads will be moving away from eachother. In consequence of these relative movements of the work and thecutter heads during the cutting operation, the ends of the head 20 ofthe work will be beveled as shown in Figs. 1, and 1 and theconfiguration of these beveled ends can be determined by the form orshape of cutting edges of the cutters used. On the return or ln'ickwardmovement of the carriage the lug or toe of lever 50 will engage the trippin 5i and break the toggle formed by this lever and the link40,----thus operating the lever 36 to raise its longer arm and releasethe clamping jaw 41-0 from the work. As the carriage recedes, the cutterheads will be moved inwardly by the operation of the cam plate 7 andafter the handle has passed backwardly beyond the cutters, the springjaws-2--Q-lwill be opened by the cam rail 3'1 and said handle can beremoved and blank placed in position, in the manner previouslyexplained. \Vhen the new blank has been placed in position, the springjaws 2324t will close and position the same and the said handle willthen be clamped, during the travel of the carriage, as previouslyexplained.

It is apparent that by providing cam plates 67 of different dimensions,and adjusting the parts of the mechanism, the machine can be readilyadapted to bevel the ends of heads of brush handles of different sizes.

Various changes might be made in the dc tails of construction of myinvention without departing from the spirit thereof or limiting itsscope and hence I do not wish to restrict myself to the exact detailsherein set forth.
